Is it possible use the same Token online and locally?

Hey guys, I need some help.

I’ve been using MasterStudy theme and I decided to change everything. However, I need to remodel the content (including plugins not used 'till now) and I would like to know how to activate my theme locally with out affect the main site (online). Is it possible? My I use the same token to activate locally and online? The idea is to make a prototype before.
